WebSep 5, 2016 · Mixed-mode chromatography (MMC) is a fast growing area in recent years, thanks to the new generation of mixed-mode stationary phases and better understanding of multimode interactions. MMC has superior applications in the separation of compounds that are not retained or not well resolved by typical reversed-phase LC methods, especially for ... WebNov 24, 2024 · In mixed-mode chromatography, the role of mobile phase pH in the retention of solute can be understood from both the influence on the solute and the stationary phase. The solutes frequently encountered in mixed-mode chromatography are mostly amphiphilic ions, that is, solutes have both polar or ionized parts and nonpolar parts.
